The Proclamation did not compensate the owners, did not outlaw slavery, and did not grant citizenship to the ex-slaves (called freedmen). It made the eradication of slavery an explicit war goal, in addition to the goal of reuniting the Union.
1 Puppy mills are dog breeding operations that put profit over the health and well-being of the dogs.  Puppy mills may be large or small. They may be licensed by the United States Department of Agriculture or unlicensed.
Overgrown nails are extremely common in puppy mills and can actually get caught in or grow around the wire and trap a dog to the cage. Nails that are never trimmed or never worn down by walking or running on solid ground often grow back into the skin.
